The WOSSNER Piston Kit measures 95.96 mm and is designed for select Kawasaki KX450 applications. It features enhanced piston pin oiling slots, radial boss machining, and annular grooves to support improved wrist pin lubrication. The lightweight piston uses tight piston wall clearance for quieter engine operation.
The piston skirt is coated to help reduce friction and improve break-in performance. Ring land treatment supports improved ring seal and oil control. A double-bridged forging design is used where noted. The kit includes the piston, rings, wrist pin, and pin locks.
